The reason is power supply of mobile phone is a battery bank, and it is very limited,if uplink frequency is more,i.e. frequency of wave from mobile phone to telecom tower is more, then large amount of power is needed to transfer this frequency,so more power should be consumed in
i recently discovered the fact that our PSTN line has a negative voltage of -44V or -48 volt. the reason is very simple :- The battery polarities are connected so that the line voltage is negative (-48 V). A negative line voltage reduces the corrosion from electrochemical reactions occurring on a wet telephone line. becouse [...]
